Thanks guys! ... this engine really packs a lot of power ... I'm looking forward to doing something special for it.
A very powerful engine for its displacement!

Another gem from Mauricio!

You must have marvelous eyesight, I kept losing it in the clouds. Got a grin from the applause and thumbs up at the end. Great sounding little engine.

Plenty of power for that Bird ! enjoyed the video!

Thank you all for watching the video and commenting on your opinions.
Ohhh the view !! ... I can still see quite well but with the help of glasses. I've already lost part of my vision, but I can still make out the fast turns in the distance ... just in case if you come to visit me one day, wear a helmet! haha...
Friends, a pleasure to share here with you.
As soon as I can, I will start working on a project for this engine.
Please, take care of everything you can, here in my city, the Covid is already reaching many people ... I hope to stay in these conditions, but without social gatherings and with all the safety elements at work. Still, the risks are present.

Friends !! .... I really want to meet you, share with you and give you a big hug.
It would be an HONOR for me to be able to teach them to fly ... it would really be an HONOR !!! .... thank you, for this gesture, it really moves me !!!..

Well friends, I think the engine deserves a better day, and today the opportunity was given.
Take an hour and I wanted to film the flight with this clear sky, the wind does not interfere with the sound of the engine, so I hope that now you can see the model better and hear the engine all the time.

What experience do you have with .074 Norvel?
I was looking at the performance of the MP-JET .061 r / c and wondering if it is comparable to Norvel's .074 r / c?

If anyone on the forum has measurements and experience with the Norvel .074, I'd like to know what they think.
If you have any video, even better.
It is a very light engine, low weight from what I can see beforehand, and apparently very powerful, but I have no experience with the Norvel .074.

Here is a video of one from Combatpigg. He seems to have quit flying recently. Mine is barely broken in, and really does not start well in cold weather. The sleeve seems to shrink down on the piston making it hard to start. Once running it is nice handling overall and is fine in the summer. https://www.youtube.com/watch?v=Wq9vd5ja-gw

The Norvel .074 is the low weight king of the no bearing type small engines up to .074 displacement.
The SH .07 has shined thru conversion to aero use on a pipe performance is excellent.

Haha, yes, been there done that...
It took me about one season before the Norvel .074 would free up enough to not need any preheating of the cylinder in the typical weather we have here.

Once broken in they are indeed great engines with an impressive power to weight ratio. Here is one of my old videos of the Norvel .074 engine, inverted and fully cowled in a Super Chipmunk:

Thanks a lot for all the information guys!
